static pos($string, $search, $fromIndex = 0)

Returns the index within this string of the first occurrence of the specified substring, starting at the specified index.

Параметры:
  • $string – string
  • $search – string - the substring to search for
  • $fromIndex – int - the index from which to start the search.
Результат:

int - returns -1 if not found
static posIgnoreCase($string, $search, $fromIndex = 0)

The same method as pos() only with ignoring case characters

Параметры:
  • $string – string
  • $search – string - the substring to search for.
  • $fromIndex – int - the index from which to start the search.
Результат:

int - returns -1 if not found
static lastPos($string, $search, $fromIndex = null)

Returns the index within this string of the last occurrence of the specified substring. The last occurrence of the empty string “” is considered to occur at the index value $string.length.

Параметры:
  • $string – string
  • $search – string - the substring to search for.
  • $fromIndex – null, int - - null means $fromIndex will be equal $string.length
Результат:

int - returns -1 if not found
static lastPosIgnoreCase($string, $search, $fromIndex = null)

The same method as lastPos() only with ignoring case characters

Параметры:
  • $string – string
  • $search – string - the substring to search for.
  • $fromIndex – null, int - - null means $fromIndex will be equal $string.length
Результат:

int
static sub($string, $beginIndex, $endIndex = null)

Returns a new string that is a substring of this string. The substring begins at the specified $beginIndex and extends to the character at index $endIndex - 1. Thus the length of the substring is endIndex - beginIndex.

Параметры:
  • $string – string
  • $beginIndex – int
  • $endIndex – null, int - When $endIndex equals to null then it will be equal $string.length
Результат:

string - return false if params are invalid
static compare($string1, $string2)

Compares two strings lexicographically. The comparison is based on the Unicode value of each character in the strings.

The character sequence represented by $string1 String is compared lexicographically to the character sequence represented by $string2. The result is a negative integer if $string1 lexicographically precedes $string2. The result is a positive integer if $string1 lexicographically follows $string2. The result is zero if the strings are equal; compare returns 0 exactly when the strings are equal

Параметры:
  • $string1 – string - - first string
  • $string2 – string - - second string
Результат:

int
static compareIgnoreCase($string1, $string2)

The same method as compare() only with ignoring case characters

Параметры:
  • $string1 – string
  • $string2 – string
Результат:

int
static equalsIgnoreCase($string1, $string2)

Checks that the strings are equal with ignoring case characters

Параметры:
  • $string1 – string
  • $string2 – string
Результат:

bool
static startsWith($string, $prefix, $offset = 0)

Tests if the substring of this string beginning at the specified index starts with the specified prefix.

Returns `true if the character sequence represented by the argument is a prefix of the substring of this object starting at index offset; false otherwise. The result is false if toffset is negative or greater than the length of this $string; otherwise the result is the same as the result of the expression

startsWith(sub($offset), $prefix)

Параметры:
  • $string – string
  • $prefix – string
  • $offset – int - where to begin looking in this string
Результат:

Результат:

int
static replace($string, $target, $replacement)

Параметры:
  • $string – string
  • $target – string - The sequence of char values to be replaced
